Application filed November '26, 1920. Serial No. 426,384.

To all'whom it may concern:

Be it known that I, GUY MARsHALL, a citizen of the United-States, andresiding at Calgary, Alberta, Canada, have invented certain new anduseful Improvements in Seat Constructions for Farming-Machines, of whichthe followingis a specification, such as will enable those skilled inthe art to which it appertains to make and use the same.

This invention relates to farming machines such as binders, mowers andthe llke and partlcularly to the seat construction of such machineswhich are adapted for use in hilly countries and where the farming isdone along a hillside and not up and down such hillside, and the objectof this invention is to provide an improved seat construction formachines of the class sp ecified lowing specification, of which theaccompanying drawing forms a part, in which the separate parts of myimprovement are designated by suitable reference characters in each ofthe views, and in which Figure 1 is an end view of my improved seatconstruction and illustrating the method of its use;

Fig. 2 a transverse sectional view of the construction shown in Fig.1,.the section being on the line 22 of Fig. 3;

Fig. 3 a partial section on of Fig. 2; and,

Fig. 4 a section on the line 4-4 of Fig. 3.

In the accompanying drawing I have shown at 5 a part of the spring seatsupport of a binding, mowing or similar farming machine, to the free endportion of which is secured my improved seat construction 6. Y The seatconstruction 6 comprises a frame the line 3-3 7, consisting of a baseplate 8 at the ends standing bearing members 11 in which a shaft 12 ismounted and a worm 13 is socured to said shaft between the bearing Imembers 11. One end of the shaft 12 is provided with a crank lever 14 bymeans of which said shaft may be rotated.

.Mounted between the upper end portions of the walls 9 and 10 is a plate15 which is free to oscillate laterally upon pins or similar devices 16passed thereinto and which are mounted in the walls 9 and 10. A suitableseat member 17 is secured to the plate 15 by a bolt 18 or in any otherdesired manner so that the seat and said plate will move laterally asone unit.

Secured to the plate 15 approximately centrally thereof is a dependinggear segment 19 which cooperates with the worm 13, as clearly shown inFig. 2, said gear segment, in the form of construction shown, beingsecured to the plate 15 by a bolt- 20 passed through a backwardlydirected extension 21 on the gear segment 19.

In the use of my improved seat construction and after the various partsthereof have been assembled in the manner shown, the same is mounted inconnection with the spring seat support 5 by a bolt 22 passed throughthe base plate 8 of the frame 7, and

V the upper end portion of the seat support 5,

as clearly shown in Fig. 3 of the drawing. It will be understood that myimproved seat construction may be used horizontally as shown in Figs. 2and 3 of the drawing, when the machine in connection with which it -ismounted is used upon level ground, but

such inclination of the hillside may be counteracted by the operatorfrom time to time by rotating the crank 14 in the proper direction.Itwill also be seen that the seat 17 of my improved seat constructionmay assume a horizontal position when the machine in connection withwhich it is employed, is on a hillside the inclination of which iseither at the right or left hand side of the machine. I

It will be understood that while I have shown certain details ofconstruction for carrying my invention into eifect, I am not necessarilylimited to these details nor to a support of any specific form andconstruction,; and various changes in and modifications of theconstruction herein shown and described may be made, within the scope ofthe appended claim, without departing from the spirit of my invention orsacrifici its advantages.

having fully described my invention, what I claim as new and desire tosecure by Letters Patent, is

In a seat construction of the class described, a frame having upstandingside and end members, a plate rotatably mounted in the top portions ofsaid end members, a seat mounted on said plate, a gear segment connectedwith the bottom of said plate and extending downwardly between the endmembers of the frame, a shaft mounted between the upstanding sidemembers and provided with a worm which cooperates with saidgear'segment, and means for turning said shaft and said worm.

In testimony. that I claim the foregoing as my invention 1- havesignedmy name in presence of the subscribing witnesses this first day ofNovember, 1920.
